Glycine in aerosol water droplets: a critical assessment of Köhler theory by predicting surface tension from molecular dynamics simulations
Glycine aerosol water Kö hler theory surface tension molecular dynamics simulations
2011/1/20
Aerosol particles in the atmosphere are important participants in the formation of cloud droplets and have significant impact on cloud albedo and global climate. According to the Köhler theory wh...
Temperature-induced volatility of molecular markers in ambient airborne particulate matter
molecular markers ambient airborne particulate matter
2011/1/19
Molecular markers are organic compounds used to represent known sources of particulate matter (PM) in statistical source apportionment studies. The utility of molecular markers depends on, among other...
Molecular hydrogen (H2) emissions and their isotopic signatures (H/D) from a motor vehicle: implications on atmospheric H2
Molecular hydrogen (H2) isotopic signatures (H/D) a motor vehicle atmospheric H2
2010/8/13
Molecular hydrogen (H2), its isotopic signature (deuterium/hydrogen, δD), carbon monoxide (CO), and other compounds were studied in the exhaust of a passenger car engine fuelled with gasoline or metha...
Scanning electron microscopy and molecular dynamics of surfaces of growing and ablating hexagonal ice crystals
electron microscopy molecular dynamics growing and ablating hexagonal ice crystals
2010/8/12
We present the first clearly resolved observations of surfaces of growing and ablating hexagonal ice crystals using variable-pressure scanning electron microscopy. The ice surface develops trans-prism...
Molecular distributions of dicarboxylic acids,ketocarboxylic acids and α-dicarbonyls in biomass burning aerosols:implications for photochemical production and degradation in smoke layers
Molecular distributions dicarboxylic acids ketocarboxylic acids α-dicarbonyls biomass burning aerosols
2010/3/5
Aerosols in the size class <2.5 μm (6 daytime and 9 nighttime samples) were collected at a pasture site in Rondônia, Brazil, during the intensive biomass burning period of 16–26 September 2002 a...
Analysis of atmospheric neutral and charged molecular clusters in boreal forest using pulse-height CPC
atmospheric neutral molecular clusters boreal forest pulse-height CPC
2009/7/1
We measured the size distribution of atmospheric neutral and charged clusters and particles down to mobility diameter around 1.5 nm by applying pulse-height CPC technique at SMEAR II station in Hyyti&...
The time dependence of molecular iodine emission from Laminaria digitata
molecular iodine emission Laminaria digitata
2009/3/13
We present the first in situ detection of molecular iodine emitted from the brown macroalga Laminaria digitata under natural stress conditions. We show that the release of I2 occurs in short, strong b...
A model for particle formation and growth in the atmosphere with molecular resolution in size
particle formation and growth atmosphere molecular resolution
2009/3/10
The formation and growth of atmospheric aerosol particles is considered using an exact discrete method with molecular resolution in size space. The method is immune to numerical diffusion problems tha...
Modelling molecular iodine emissions in a coastal marine environment: the link to new particle formation
Modelling molecular iodine emissions coastal marine environment particle formation
2009/1/5
A model of iodine chemistry in the marine boundary layer (MBL) has been used to investigate the impact of daytime coastal emissions of molecular iodine (I2). The model contains a full treatment of gas...
Technical Note: Molecular characterization of aerosol-derived water soluble organic carbon using ultrahigh resolution electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry
aerosol-derived water soluble organic carbon ultrahigh resolution electrospray ionization ion cyclotron resonance mass spectrometry
2008/11/18
Despite the acknowledged relevance of aerosol-derived water-soluble organic carbon (WSOC) to climate and biogeochemical cycling, characterization of aerosol WSOC has been limited. Electrospray ionizat...
